Not a ton to say here- this is beautiful tree lined street that connects the old palace with the congress building. It's worth a stroll from end to end. It has lots of classic French architecture that was erected when the city celebrated Argentina's centennial in the late 19th century. You really feel like you're walking around Paris on a spring day. You'll often see protests and gatherings as these are popular community congregation sites. Great area to bum around for half a day or so.
